Bitcoin is the best coin in crypto and as the years passed by there are a lot of coins (altcoins) that is more profitable in terms of investment on both short and long term process, in you're future sights and speculation of btc based on some good promising projects that is now scattering and has a posibility to move to next level in the near future, Can there will be a coin that can manage to surpass btc 10 years from now?
I would love to see the coins that you are referring to.
While indeed short-term, there can be some coins in the top 20 that can overtake bitcoin in terms of profitability specially in a good alt bullrun, it cannot be as good as bitcoin in the long run because if you have been around in this industry for a while, you will see that the rankings change a lot and some coins that were pretty good and had good utilities have removed from the list. There are good shitcoins as well that can also over take bitcoin in terms of profitability but this takes a lot of luck(not worth it) or skill which can still pose some risks(risks depend on your skills and temperament towards your investments).
So, which coin is truly profitable and will there be any coin that would surpass bitcoin?
The way I see it, this depends on the type of investor you are; how much time you can dedicate in crypto investing, risk tolerance, knowledge, experience, emotional control and so much more. Because not every investor has the same capital, same mindset, same techniques, schedules etc. It would be much better to stop comparing and start searching for what routines and ways fits you best and gives you the maximum potential of profitability through trial and error.
As for surpassing bitcoin, I don't see it happening in the near future. Bitcoin right now is just too dominant in terms of popularity, ease of access and usage. I don't know though in the far future but in my lifetime, I think I will only see bitcoin as the one on top.
